I have noticed that many people have been asking for a paper kunai instructable. I happen to know how to make them, so I decided to put my account to use. I'm sorry if you were looking for a throwable kunai, because I've tried many ways to throw this one and have not found any. Maybe I just stink at throwing kunai, I don't know. This kunai is good for holding and twirling on your finger, though. The kunai handle is a bit short for my liking, but I made this kunai late at night and I was way too lazy to fix it. I was already rather far in the kunai making and picture taking process. Oh, and as for the picture quality, I took these pictures with my cell phone. I do not own a digital camera, and like I said, this kunai was made late at night. If there is anything that needs clarifying, do not hesitate to ask. Please understand that this is my first instructable. Thanks, and I wish you all luck making your kunai. -RachelisBored95

Step 1: Materials

You will need:
1. 2 pieces of paper (I used computer paper)
2. Tape (I guess liquid glue would work too, but tape is easier to use)
3. 4 pennies (Optional, for added weight)
4. A pencil (Not exactly necessary, it just helped me to form the handle and the ring)
5. Scissors (If you aren't very good at ripping paper, or want a cleaner looking kunai. I personally just rip my paper.)

Step 2: Blade and Sheath

1. Fold one of the pieces of paper into fourths. Cut/rip.
2. Take one of the fourths and fold it in half along the line shown in the third picture
3. Fold the paper as shown in the fourth picture, using the middle line as a guide. It should look like the fifth picture.
4. Fold along the line in the sixth picture, again using the middle line as a guide. It should look like the seventh picture.
5. Fold along the line shown in the seventh picture(Yet again, using the middle line to help you. Don't you just love the middle line?). It should look like the eighth picture.
6. Make 3 more of these. In the end you should have four.
7. Put two of the triangles together as shown in the tenth picture. It should look like the eleventh picture. Tape together.
8. Make another of these using the other two triangles. You should now have two. One of these, you can set aside. It will be used as the sheath for the kunai. The other will be used for the blade.

Step 3: Kunai Handle and Ring

1. Take the other piece of paper and cut/rip it into fourths
2. Take two of the fourths and lay them horizontally. Tape. You can also add a third fourth onto the middle of the first two for added strength.
3. Use the pencil(If you decided to use one) to roll the paper into a tube. Tape the tube. It should look like the fourth picture. This will be your handle.
4. Take the other fourth and lay it horizontally. Roll it into a smaller tube. Tape. It should look like the fifth picture. Flatten the tube to look like the sixth picture.
5. Trim the flattened tube to make a ring the size of your choosing. It should look like the seventh picture.

Step 4: Forming the Kunai

You should now have all the parts shown in the first picture.
1. If you decided to use pennies, put the pennies into the blade(Second picture. Oh look, my hand!)
2. Insert the tube into the blade
3. Flatten the end part of the handle
4. Put the ring onto the flattened part of the handle(Sorry, no picture)
5. Loop the flattened part of the handle through the ring. Tape. It should now look like the fifth picture
6. Fold the corner of the blade as shown in the sixth picture
7. Do the same for the other corner. Tape. It should look like the seventh picture.
8. Insert the kunai into the sheath. If you were able to follow this entire instructable, you now have a finished kunai and sheath. Good job!
<p>awesome! soo kool</p>
<p>Wow this was easy it took me awhile to get which step went with what pic but i managed.</p>
<p>i made it only in ten minutes</p>
i put silver tape on the blade
I made 2 and joined it with a small paper chain so it's like knife nunchuks :)
i made it and it really works goooood my friends got shocked
cool id give it 8 out of ten but can u make clean looking paper gun like a sniper???????
so cool! This is so awesome!
this waS EASY AND fun
while folding the paper hamburger (vertical) style, don't make the fold DIRECTLY in the middle, make the fold slightly off center to have a bigger sheath than blade and shave the top of the sheath off. this looks cooler.
ok
i perfected it by making a belt loop on the sheath <br>
Lol pennies xDDDD if you didnt get it - penis
so goood i like it, mines turned great
that was so awesome dont worry about taking pictures with your phone they were great
thanks a bunch, i will be putting this in my first instructable, and i am definately giving credit .
I saw your Instructable. Pretty good, I have to say! :)
thanks a bunch! got an idea for a new ninja device, so i'll post it ASAP!
hey toxicity, i made this and i realy love it, you did a great job on the instructable but i don't know how to throw it, could youo help me?
haha my friend tought me how.&nbsp; spin it by the wring on your finger, then release the muscles in your finger and point your hand in the direction you want it to go. hope that helped!
cool ive made 5 already and love hitting my bro with them
amen to that. lil bros are da best target, especialy when they get mad. :-P
On the contrary. Older brothers are the best target. Their reactions are priceless!&nbsp;xD
dito}][{<br />
I know right
I have like 20 of them and it's really funny seeing my little brother not knowing where they are coming from XD
How old is he? 3
&nbsp;Here's a pic of my ninja weapons, using your special kunai recipe with a couple of modifications&nbsp;
&nbsp;also a way to make the whole kunai hold together better is to use hot gule where you combining 2 peices or to make the tip heavier and stronger :D
&nbsp;by filling the tip with glue
this is a great instructable, but it doesn't throw straight :( any suggestions?<br /> <br />
&nbsp;Awesome! Maybe you could&nbsp;find a way to make the tip stronger. <br /> business&nbsp;card?
&nbsp;I used the sheath as a second layer for the blade and put son cardboard (from a beer box :P) which made the tip heavier and stronger (cut the cardboard to fit in less then half of the blade NOT for the entire blade, so its better balanced) and im painting my kunai black for more realisticness
if u take this, and tape the blade on all sides, take the sheath and tabe it on there, but leave the sides open, u can have enough weight w/out the pennies to throw it like a dart. will make an instructable how to do it, and give u a link on each page how to make urs, kay? is it? HUH? ill find u and steal ur puppy dog and pet it until it likes me best and wont love u anymore if u say no!
k im wwatting<br />
A) I don't have a puppy... o_O B) Go ahead, just give me credit for the original kunai! :)
u should keep the pencil in the handle<br />
coolioawesomeness!
Me and a friend at school are making a Paper-Ninja Armory. So far we have about 60 throwing stars, 20 throwing squares, and now, one of these.&nbsp;I plan to make more. <br /> Great instructable. Faved, and rated 5*<br /> Anyone know of any more good paper-ninja weapons?<br />
On what exactly?
naruto things<br />
this thing is awesome
Haha Narutard. Nah jokes...But some naruto people are pretty annoying. Anyway, this seems pretty cool. But been 13 yrs old...Id rather make one out of some wood and sheet/strap steel. Theres probable an ible on metal/wood kunais somewhere...
... Guess what the first result was when i searched "Kunai"? K'nex Kunai Im resisting the urge to pulverise something.
I <strong>HATE</strong> that, its so annoying. I just wanna kill someone with my new KUNAI.....heh
hahaha i know right?
Yea, those tend to appear A LOT. Try searching google, perhaps?
haha ive been trying to make one out of wood
if you want to add weight, try quarters, and duct tape. As for throwing, it think i will make an instrucable one of these days for throwing, i can cut a leaf in half from about 4 feet with a garden trowel (which is what a kunai basicly was) but the thing isnt straight so i cant get accurate with it. but overall, GREAT JOB!!!!!!!!!!!! one of these days i will make one, im feeling to lazy right now
